I have a 360 buckhammer G2 contender 18” barrel from SSK. I stated to load this cartridge with way slow burning powders. H4895 was first and then benchmark velocity was too low with a full case of powder with these two. Next was H4198 and looked like a good fit but wanted to get a little more velocity so tried H4227 which gave more velocity but started to have high pressure signs.
Went back to H4198 using the Speer 180 grain bullet seated to the cannelure got a little over 2100FPS using 30 grains of powder in formed PPU 30-30 brass. Fired case looks fine no real pressure signs at all. I feel this load is safe in my barrel I worked up this load starting at 26 grains, so if you want to try it for yourself start there and work up for your rifle.
For now this gets me close enough, and will wait for load data from Hodgdon. I am interested in which powders Hodgdon specs for this cartridge.
